Embodiment
With reference to the accompanying drawings the present invention is described in more detail, exemplary embodiment of the present invention wherein is described.In the accompanying drawings, identical label represents identical or similar assembly or element.
Fig. 1 is the synoptic diagram according to the application scenarios 100 of the embodiment of the invention.Application scenarios 100 comprises vehicle 102, information-recording apparatus 104.
Information-recording apparatus 104 can be the amateur terminal that mobile phone, PDA etc. possess shooting, direction sensor (such as electronic compass), alignment sensor and time function.For the clear information-recording apparatus 104 that illustrates, it is amplified expression among Fig. 1.
The information such as beginning periodicity document image, direction, location and time in vehicle 102 traveling process.When can't obtaining, locating information also can only record other data.Carry out aftertreatment as one group of data after having recorded the information of road one side, the road opposite side then carries out aftertreatment as another group data.Can comprise rejecting to repeating data to the aftertreatment of data, and the completion elements of a fix etc.
Fig. 2 is the process flow diagram according to the information acquisition of the embodiment of the invention and disposal route 200.
In step 202, on the vehicles of fast moving, gather one group and comprise multiple image, and take the time of every two field picture and the data of shooting direction.
In step 204,, shooting direction a plurality of records identical and asynchronism(-nization) identical to the image in these group data only keep a record.
In step 206, record the elements of a fix that comprise according to the first record and the 3rd, reckoning does not have the elements of a fix of the second record of the elements of a fix, wherein, in all elements of a fix of these group data, the time that gathers the first record and the 3rd record is record the most contiguous before and after the time that gathers the second record.
Fig. 3 is the process flow diagram of according to another embodiment of the present invention information acquisition and disposal route 300.
In step 302, on the vehicles of fast moving, gather one group and comprise multiple image, and take the time of every two field picture and the data of shooting direction.The vehicles can be motor vehicle, motorcycle etc.Information-recording apparatus can be the terminal that mobile phone, PDA etc. possess shooting, direction sensor (such as electronic compass), alignment sensor and time function.In one embodiment, the shooting direction of information-recording apparatus can be consistent with the direction of direction sensor, and fix at an angle θ with the line direction that travels of the vehicles.This angle can be used in aftertreatment the directional data that records being converted into garage's directional data.For the POI point in recording channel roadside clearly, preferred, θ can be 90 degree, and it is vertical with vehicles travel direction namely to take direction, make take direction can be over against road one side.
In step 303, can vehicles switch area be separation, obtain at least two group data.Because when head end operation, what camera was right is the POI information in road rather than roadside, is unnecessary information.The tune angular transformation 180 degree, the follow-up approximate coordinates completion of the method operates in angular transformation and has larger deviation when excessive, thus integrated data processing is convenient and accurately angle consider the switch area to be separation
In step 304,, shooting direction a plurality of records identical and asynchronism(-nization) identical to the image in these group data only keep a record.After having recorded one or more groups data, the aftertreatment flow process can be manually started, also the aftertreatment flow process can be automatically started.In the aftertreatment flow process, can automatically finish and pick retry.Namely to successively contrast in one group of data of record.Owing to be the journal image, therefore only need successively comparison.When finding multiimage, record of deletion from these group data.And adjust the time of these deleted follow-up all records of record, namely reduce the relative time of a record period, the time is adjusted forward one-period.
In step 306, record the elements of a fix that comprise according to the first record and the 3rd, reckoning does not have the elements of a fix of the second record of the elements of a fix, wherein, in all elements of a fix of these group data, the time that gathers the first record and the 3rd record is record the most contiguous before and after the time that gathers the second record.After having recorded one or more groups data, the aftertreatment flow process can be manually started, also the aftertreatment flow process can be automatically started.In the aftertreatment flow process, can automatically finish coordinate completion operation, namely on the way locating in the successful situation has the image information of record coordinate to pass through certain interpolation arithmetic acquisition coordinate information in conjunction with taking orientation and time by front and back, and making this organize all images has coordinate information.
Such as, be partitioned into direct ratio, the elements of a fix of DR position point B according to air line distance and the relative time of the location point C of location point B to the three records of the air line distance of the location point A of location point B to the first record of the second record and the second record.
As shown in Figure 4, take a C as initial point, AC is X-axis, sets up rectangular coordinate system, and the coordinate of then putting A is (a, 0).Wherein a=|AC| can calculate acquisition by the coordinate figure of A and C.
In the shooting direction of an A, B, C and the travel direction angle theta of the vehicles, respectively obtain straight line D with the travel direction of the vehicles according to information-recording apparatus
1, D
2, D
3, wherein, the vehicles are successively through an A, some B and some C.Such as, electronic compass direction and the equipment upper and lower side of mobile phone are wired to the right angle, and the measurement of θ is the angle of equipment upper and lower side line and garage's direction.Therefore, the travel direction of the vehicles is exactly 90+ θ.If mobile phone is parallel to vehicles direct of travel, the direction that then is exactly equipment records turn 90 degrees counterclockwise.
Scenario is positioned at an A and C top (some B is positioned at the situation of below and can analogizes) for some B, because these three points are points on the vehicles are advanced, the record period interval is close, and for the situation that does not occur two or more flex points between an A and the C, D2 only may translation in the diagram dotted line.
According to y=k
2X+b obtains straight line D
2Straight-line equation, wherein, k
2Be D
2Slope.
According to a B and some A, and the time interval of some B and some C, establishing n|AB|=m|BC|, n and m are integer, the elements of a fix that then obtain some B are (n*a/ (n+m), k
2* n*a/ (n+m)+b).Wherein, b can obtain an empirical value by test, such as the intermediate value that can get two dotted lines.
In step 308, data are converted into POI information or door location information.Such as, in image, identify house number and other Word message, with Word message and corresponding combinatorial coordinates formation POI and the door location information of this image of these extractions.
Conventional P OI information acquisition is often adopted professional equipment in order to guarantee accuracy, and a point of some ground gathers, although the POI position that gathers like this is very accurate, data acquisition efficiency is not high.In fact for application such as navigation, not high especially to the positional accuracy requirement of POI, have necessarily for the POI status requirement simultaneously to stress, such as POI on any bar road, which side on the road can not have deviation, as for the absolute position, differs from tens, 20 meters and all can tolerate.
According to an aspect of the present invention, easy information acquisition and disposal route can be based on non-professional information collecting device (such as mobile phone) and post-processing technologies, for the LBS such as navigation use Quick for the original analysis data of the POI information that satisfies application demand and door location information.Thereby can further make POI information acquisition efficient apparently higher than the acquisition means of single-point.
